Mark Sanchez, savior of Philadelphia football and part-time pretend lifeguard, is many things.
The Sanchize is a man of the people, as well as an enjoyer of Philly cheesesteaks and the finest chicken fingers NFL craft services can buy.
What he is not is a singer, as he proved at some karaoke bar in Philadelphia on Tuesday night.
Philly radio host Jon Marks (h/t BustedCoverage.com's Joe Kinsey) posted video of Sanchez shredding every last fiber of his vocal chords to the Backstreet Boys' "I Want It That Way" at Yakitori Boys—a Japanese pub and karaoke joint in the City of Brotherly Love.
